>> reporter: the carnival ceo went to apologize to passengers. when it comes to compensation, carnival has the upper hand. >> you have this contract that just takes away all their rights that the passengers who never read this agreed to it when they clicked and bought their cruise. >> reporter: carnival is offering to refund each passenger's cruise price, an additional $500 and a voucher for another similarlyly priced cruise. >> in part because they're a lightly regulated industry, the cruise lines when it comes to u.s. regulations. >> reporter: in fact, if the ship sank property damage is limited to $100 per room and a death is limited to just $60,000. >> we're not compensated for trauma, emotional distress, the breach of the criminal. all of this type of stuff they have contracted away and said i will not be part of a class action suit. i will not go to trial.
